Does perioperative hypothermia after primary total hip and knee arthroplasty affect acute outcomes?

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Intraoperative hypothermia (HT) is commonly experienced among patients undergoing total joint arthroplasty (TJA) and may be associated with increased blood loss, pain, and complications. Our study evaluated acute outcomes of patients with and without HT after primary total hip (THA) and knee arthroplasty (TKA). Methods: We identified 220 postoperative HT TJA cases (119 THAs and 101 TKAs) at a single institution as defined by a body temperature of <96.8° Fahrenheit (F) immediately in the post-anesthesia care unit (PACU). Cases were matched to non-hypothermia (NHT) controls 1:2 based on procedure type, age, sex, and body mass index. Intraoperative, immediate PACU, and 90-day outcomes were compared, including vital signs, blood loss, pain scores, opioid use, length of stay (LOS), complications, reoperations, Hip Osteoarthritis Outcome Score, Jr (HOOS), and Knee Osteoarthritis Outcome Score, Jr (KOOS). Results: HT patients after THA and TKA did not experience significant differences in immediate PACU or hospital-based outcomes, including vital signs, pain scores, opioid consumption, LOS, or home discharge ( Conclusion: TJA patients experiencing perioperative HT do not have clinically significant different acute recovery and 90-day outcomes compared to NHT controls. While surgical patient normothermia remains important, both anesthetic and surgical considerations should be factored into determining the most optimal operating room temperature.
